Jim Jessop is fed up with lithium-ion battery fires.

Toronto’s fire chief sounded off on social media after his crews responded to three separate fires involving the increasingly problematic batteries, including one that escalated to a two-alarm response level.

Around 6 a.m. Wednesday morning, crews were called to the George Street and Dundas Street East area for reports of an e-bike battery fire.

According to reports from the scene, the fire occurred in a fourth-floor unit of an apartment building. One of several e-bike batteries in the space caught fire. A tenant then reportedly threw it in the bathtub.

Four people were cared for by Toronto paramedics at the scene. One was taken to hospital with non-life-threatening injuries.
